Okay, I figured it out. It turns out the problem was that the magnetic field inside the solenoid
was not given by that expression for B, but was actually given by a rather intricate expression
with bessel functions and such.
Anyway, here is a link to an article discussing just this, if...
Hello!
I am making som calculations on induction heating of a metallic cylinder inside
a solenoid through which an AC current passes, but the answer I get seems to
be completely unrealistic (10 kW with a 50 Hz, 5 Amps, 230 V rms), but I can't seem
to find my mistake.
What I think is...
I see. So in the example with the two astronauts, whose clock will tick faster depends on the frame of reference you choose, and to both of them it will look as if the other astronaut's clock ticks slower?
And in the case with a spaceship traveling near c, the astronauts will age less not...
I have just started studying special relativity, and there is one thing I really don't understand:
Suppose you have two observers, A and B, in space, and that these are moving relative to one another. Due to time dilation, their clocks will tick at different rates. But how do you know whose...
Use conservation of momentum on the first one. If they are both at rest at the beginning, and the student starts walking, then the boat will get a momentum that is exactly
as large as the student's, but in the opposite direction (inverted signs).
As for the second one, I'm not really sure...
Problem 1
Homework Statement
Prove that p^2 - 1, where p is a prime greater than 3, is evenly
divisible by 24.Homework Equations
The Attempt at a Solution
p^2 - 1 can be written as (p+1)(p-1)
Since p is a prime, (p+1) and (p-1) must both be even numbers.
Since every third integer is divisible...
